The delivery error. For example, the carrier substrate 1〇2 is often a glass substrate or a rigid plastic substrate such as polycarbonate. Since the glass substrate can withstand a relatively high temperature, when the glass is used as the carrier substrate 102, the first transparent conductive film 104 is, for example, a transparent conductive film directly plated on the glass substrate. However, the texture of the glass substrate is easily broken, and the touch panel 100 is also increased in weight. • * Hard plastic substrates such as poly-sour vinegar are lighter and easier to mold, but they cannot withstand the high temperatures of the sputtering process. Therefore, when a polycarbonate (PC) substrate is used as the carrier substrate 102, the first transparent conductive film 104 must be a PET film coated with a transparent conductive film. The PET film with a transparent conductive film in this mine requires an additional film coating process to adhere the PET film to the rigid plastic substrate. Therefore, the bonding process of the PET film and the substrate causes an increase in production cost and a decrease in yield due to the filming process. As a result, not only will the cost of production be increased, but the thickness of the touch panel itself will also increase, resulting in a lower transmittance of visible light. SUMMARY OF THE INVENTION The present invention provides a method for fabricating a transparent conductive film to solve the problem that a hard and plastic substrate cannot be transparent to a transparent conductive thin lining. The present invention proposes a method of fabricating a transparent conductive film, which comprises the following steps. First, a reaction chamber is provided in which the reaction chamber has a Zdooztwr.aoc/n material of at least 6 201016872 and at least one heating device. Then, in the reaction chamber, the electric glory is located above the sister. Then, using the heating device, the temperature is raised to the temperature of the Wei, and the hard: special rate is passed over the plasma, wherein the dry material after the impact is deposited in the hard (4) A transparent conductive film is formed on the adhesive substrate. . In the embodiment of the invention, the above standby temperature is C. . In one embodiment of the invention, the above operating temperature is 〇 °Ci 45 〇 C. In an embodiment of the present invention, in the case where the hard plastic substrate passes over the plasma, the manufacturing method further includes pre-processing the hard substrate. The pretreatment process is, for example, coating a layer of material having a thickness of several tens of nanometers on a rigid plastic substrate, the composition of which includes chromium, tantalum, chopping or a combination thereof. In an embodiment of the invention, before the hard plastic substrate passes over the plasma, the manufacturing method further comprises performing a second preheat treatment on the rigid plastic substrate. For example, the preheat treatment process temperature is from Sichuan to 130. In an embodiment of the invention, the hard plastic substrate is made of polycarbonate (PC). In an embodiment of the invention, the material of the target material comprises a metal oxide of indium tin or indium zinc which is composed of different proportions. In one embodiment of the invention, the higher the operating temperature, the faster the specific rate. When the rigid plastic substrate passes through the reaction chamber, it will firstly heat the environment at a high temperature via a 201016872 zouj^iWL.uOC/n, which will help to improve the conductivity, material and quality of the transparent conductive film. In addition, the time during which the rigid plastic substrate passes through the reaction chamber can be changed by the temperature of the iXPic reaction chamber to avoid the plastic substrate being changed. The present invention provides a method for forming a transparent conductive film on a rigid plastic substrate. The above and other objects, features, and advantages of the present invention will become more apparent from the aspects of the invention. [Embodiment] Since the plastic substrate itself has a low temperature range, the transparent conductive film cannot be directly applied to the plastic substrate by a conventional sputtering method. Therefore, the application range of the plastic substrate is greatly limited. For the reason of this, the present invention proposes a method of producing a transparent conductive film, which can form a transparent conductive film directly on a rigid plastic substrate and have a good conductive property of the transparent conductive film. In addition, such a manufacturing method does not cause the rigid plastic substrate to be deformed or damaged by heat. 2 is a top view showing a manufacturing process of a transparent conductive film according to an embodiment of the present invention, and FIG. 3 is a side view showing a manufacturing process of a transparent conductive film according to an embodiment of the present invention. Referring to Fig. 2 and Fig. 3 together, the method for fabricating the transparent conductive film of the present embodiment includes the steps described below. First, a reaction chamber 200' is provided in which the reaction chamber 200 has at least one target 210 and at least one heating device 220. The material of the target 210 may include metal oxides of indium tin or indium zinc in different proportions. Of course, the material of the target 210 is also 201016872 ^OOJZ.LWl.U〇C/l\ other conductive materials may be used, and the invention is not limited thereto. this. In one embodiment, the ratio of the composition of the indium tin metal in the target 210 to the composition ratio of the indium zinc metal can be adjusted with different processes or product requirements. For example, the ratio of the tin metal component in the target 210 may be 2 to 15%. However, the above-described composition ratios are for illustrative purposes only and are not intended to limit the scope of the invention. Then, a plasma 230 is generated in the reaction chamber 200, and the plasma 230 φ is generated, for example, above the target 21 〇. The plasma 230 is composed of, for example, particles of a charged gas molecule, a gas atom, an electron or the like. These particles in the plasma 23 have a certain energy to strike the surface of the target 21, so that the particles on the surface of the target 21 are detached from the target 21 by the bombardment of the plasma 230. These particles detached from the target 210 will be deposited on the surface of the other material by sputtering to achieve the effect of demineralization. In this embodiment, after the slurry 230 is generated in the reaction chamber, the plasma 23〇 is first maintained in the standby state, and the standby temperature in the reaction chamber 200 is, for example, 〇<t~2〇(rc). The heating device 220 is used to heat the plasma 23 from the above-mentioned standby temperature to the operating temperature and the hard plastic substrate 300 is passed over the electropolymer 230. At this time, the plasma 23 〇 strikes the target 21 The particles on the surface of the target 21 are detached and deposited in a -surface manner on the substrate 3 to form a transparent conductive film 310. In this step, the reaction chamber will be lifted to about 〜C~450 °C. The working temperature is the same as in the present embodiment. The heating device 220 is mainly for the plasma 230 plus the dry electricity t 230 and the particles that are struck from the m 2! 同时 have the energy of the 杈南. So - will benefit The material 21〇 is struck out of the 201016872Qoc/n particles to form a transparent conductive film 310 having better mechanical strength and physical properties on the rigid plastic substrate 300. Generally, the transparent conductive film 310 has better physical properties. For example, the conductive impedance is low. Therefore, this embodiment uses the instant The heating action causes the dry material 210 to obtain higher energy to form a transparent conductive film 310 having better conductivity. Further, in this embodiment, the rigid plastic substrate 300 is passed over the plasma 230 at a specific rate v. Rather than being fixedly placed above the plasma 230, the rigid plastic substrate 300 is not deformed by excessive heat. In other words, the present embodiment can be formed on the rigid plastic substrate 300 before the rigid plastic substrate is deformed. Conductive film 310. It is worth mentioning that the specific rate V of the hard plastic substrate 300 through the plasma 23 () is actually related to the environmental operating temperature condition control. When the operating temperature is higher, the hard plastic substrate 300 passes through the plasma 230. The specific rate V at the top needs to be increased. Conversely, the hard plastic substrate 3 can be slower through a specific rate v above the plasma 230. The rigid plastic substrate 3 (8) • can be placed, for example, on a vehicle for control The rate of the trolley changes the specific rate v of the rigid plastic substrate 300 through the plasma 230. In this embodiment, in order to monitor the reaction Temperature change in the body 2 ' The reaction chamber 200 may be provided with, for example, a temperature sensing device 24 〇. The temperature sensing device 240 may be a thermoelectric shank that protrudes into the interior of the reaction chamber to sense electricity. The temperature of the poly 230 is changed. Of course, the temperature sensing device 24 can also be used for other temperature sensing devices, and the present invention is not limited thereto. In addition, the present embodiment sets the operating temperature to 〇t:~45 (rc as an example). However, in other real 201016872 zo〇jziwi-ii〇c/n examples, the operating temperature can also vary with different needs. In short, the higher the operating temperature of the environment, the higher the energy obtained by the electricity |23G. The transparent conductivity Γ Γ Γ conductivity will also be significantly improved, but limited by the hard plastic film = 30 = its own heat resistance is low. Therefore, in the manufacturing method of this embodiment, the working temperature of the soil must be controlled within an appropriate range, and the basin should not be heated without limitation. In order to improve the adhesion between the transparent conductive film 310 and the rigid plastic button 300 before the above-mentioned process step, the present embodiment can perform a pretreatment process on the hard substrate 3GG. This process involves the formation of a pretreatment layer (not shown) on the surface of the rigid plastic substrate. The material of the pretreatment sound (not included) includes chromium, 7, oxygen cut or a combination of the above. When cooked, the material of the pretreatment layer (not shown) is not limited to this. In other process steps, other (4) layers may also be selected as the layer (not shown). In addition, before the hard plastic substrate 3 passes through the reaction chamber 2, the embodiment can further perform a pre-heat treatment on the hard plastic substrate, and the process temperature of the pre-heat treatment is, for example, thief to 13{rc. When the preheated rigid plastic substrate passes over the plasma 23Q, the temperature of the particles of the dried dry material 210 is closer to the temperature of the hard f-flap substrate 3 (10). As a result, not only can the mechanical strength of the transparent conductive film 31〇 be increased, but also the physical properties of the overall transparent conductive film 310 can be significantly assisted. It is to be noted that the material of the hard plastic substrate 3 (9) of the present embodiment is, for example, a process temperature of, for example, no more than 13 Å from the purpose of the polycarbonate treatment to avoid the hard-to-substrate survey line shape. (4) The material of the valve substrate 3 can also be polymethyl acrylate vinegar (pMMA), polyparaphenylene 11 201016872 - a 〇 c / n dicarboxylic acid ethyl ester (PET), triacetate fiber (TAC), Polyimide (PI) and other materials. If the hard plastic substrate 300 is made of other materials, the process temperature of the preheat treatment can be changed. Furthermore, generally, after processing the rigid plastic substrate 3, most of them will pre-bake the substrate first, and then placed in a vacuum chamber to help the surface moisture. Effectively removed. Further, before the hard plastic substrate 300 is subjected to coating processing, an activation process may be performed on the surface φ, which is, for example, a plasma process to activate the surface of the rigid plastic substrate 300. Of course, the manufacturing method of the present invention is not limited to the above-described pre-processing steps. In general, the lower substrate of the touch panel is generally subjected to a filming process in which a plastic film (for example, a PET film) coated with a conductive film is attached to the rigid plastic substrate 300. . Problems that may occur in this filming process. · In addition to the problem that the conductive film is easily peeled off, the process of filming will also cause a drop in product yield. Compared with the conventional design, the touch panel of the present invention can not only remove the additional film process, but also greatly improve the process yield, and at the same time, the rigid plastic substrate forming the transparent conductive film 310 of the embodiment is applied. 300, not only can make the touch panel have better penetration rate, and the hard plastic substrate 3 〇〇 easy to process and light weight characteristics can help to compensate for the shortcomings of the glass substrate. The transparent conductive film 310 obtained by the present embodiment has a good physical property, and particularly the conductive stability is also remarkably improved. With the production method of this embodiment, the degree of crystallization of the ITO film formed on the PC substrate can be comparable to the degree of crystallization of the ITO film formed on the glass substrate, and

For example, the general touch panel requires that the resistance change rate of the transparent conductive film can be less than 25% after 72 to 24 hours at a high temperature of 8 G ° C or at 60 ° C and 90% relative humidity. Therefore, the rigid plastic substrate 3 having the transparent conductive film 310 formed by applying the embodiment will also have better signal transmission quality on the touch panel. Of course, this embodiment: the rigid plastic substrate 3 formed with the transparent conductive film 3i is not limited to being applied to the touch panel. 201016872 = To a good special / life. Fig. 4 is a green graph showing a comparison degree of crystallinity of the present invention. Referring to FIG. 4, the diffraction curve is based on the Xf crystal diffraction pattern of the iota film formed on the pc substrate according to the method of the present invention, and the diffraction pattern represents the conventional method using the conventional method. The X-ray crystal diffraction pattern of the 1τ film on the substrate. - Generally, because the temperature resistance of the glass substrate is good, the degree of crystallization of the ΙΤ0 film on the glass is significantly better than that of the plastic material. Therefore, the peak of the diffraction angle of each of the ruthenium films is remarkable as shown by the diffraction curve. As is apparent from Fig. 4, the ruthenium film produced by the production method of the present embodiment has a sharp peak at the diffraction angle of each feature. Therefore, Fig. 4 can further explain that the production method of the present embodiment can produce an iotazo film having a good degree of crystallinity. FIG. 5 shows a touch panel according to an embodiment of the present invention. Referring to FIG. 5, the touch panel 500 includes a rigid plastic substrate 3A, a transparent conductive film, a transparent conductive film 510, and a plurality of spacers 520. The transparent conductive film 31 is formed, for example, by the above-described process, and is directly disposed on the rigid plastic substrate 3A. The transparent conductive film 510 is disposed on the rigid plastic substrate 3 and is disposed on the transparent conductive film 510. The film 510 is over the conductive film 310, and the spacer 52 is interposed between the transparent conductive film 310. It consists of a transparent conductive PET film. In the present embodiment, the conductive film is directly formed on the hard plastic substrate 300, and is not formed on the pΕτ film and then attached to the hard plastic substrate 300. Therefore, the thickness of the touch panel 5 减少 is at least reduced by a conventional film design. In addition, the process of the touch panel 500 does not require the PET film to be attached to the rigid plastic substrate 3, so that no additional problems are caused by the coating process. In other words, the process yield of the touch panel 500 can be further improved. In summary, when the rigid plastic substrate is subjected to a process of instantaneous heating of the reaction chamber while passing through the target, a transparent conductive film having better physical properties and mechanical strength can be obtained. At the same time, the control of the traveling speed of the trolley can also prevent the rigid plastic substrate from being deformed due to overheating of the reaction chamber. Therefore, the method for producing a transparent conductive film of the present invention can form a transparent conductive film having good physical properties, and can also prevent deformation or damage of the rigid plastic substrate. The present invention has been disclosed in the above preferred embodiments, but it is not intended to limit the invention to any of ordinary skill in the art, and may be used in the spirit and scope of the present invention.
